Script bridge callbacks?

Question

I use Ruby to check the position of the video that I play in Quicktime through the Scripting Bridge.

For the moment, I'm just checking the position so that every nsecond:

require 'osx/cocoa'

include OSX
OSX.require_framework 'ScriptingBridge'

app = SBApplication.applicationWithBundleIdentifier_("com.apple.QuickTimePlayerX")

while true
  app.documents.each do |doc|
    p doc.currentTime
    p doc.playing
  end
  wait(n_seconds)
end

This is a more intensive processor than I would like, is there a way to get the script bridge to run the Ruby block when a particular event occurs?

eg. When does a document open, close, pause / resume, etc.?

Thanks in advance!
